Abstract (en)

A network (100) is operated by the network manager and a network (101) is used by the end users, while a policy server (104) is connected logically to one router (101a) and a network management server may be included in the network for managing the devices in the network. The policy server stores a network resource operation policy and generates instructions using the policy, a resource request and usage status information. Independent claims are included for a network resource reservation method, for a policy server and a network resource reservation program.

A network system including at least one end node (102) connected to a network and a policy server (104). The end node (102) issues a network resource reservation request. The policy server (104) stores therein a network resource operation policy and network resource usage status information and accepts the network resource reservation request issued by the end node. Then, based on the network resource reservation request and on the stored operation policy and usage status information, the policy server determines network resource reservation and issues to an associated network device a control instruction executing the determined network resource reservation. <IMAGE>
